Product Description
New Old Stock MP42B (MП42Б) USSR/Soviet Transistor. PNP Germanium.
Most of these are very low leakage, anything leaky or unstable has been sorted out.
Choose your hFE range, higher number is higher gain.
*Note, germanium is temperature sensistive, these were measured in a warehouse that is about 70°F. Tested with RG Keens method. Anything unstable was rejected. Leakage is below 300uA unless otherwise specified. These hFE ranges are meant to be ballpark ranges and it is not guaranteed that your transistor will fall perfectly in that range. Example, if you choose 80-90, it might be 75 or 95, but it will not be outrageously outside the selected range.
